There are too many cheaters and they're now even leaving messages to show that they're cheating. Devs need to put in a limit on how fast it'll accept responses to the images. The recharge button doesn't seem to work after you've clicked it a few times even if you have plenty of BTC.

EDIT:/ There is also a cheat the top "players" are using where the last word is always incorrect no matter whether you type it right or not.

why dont you guys add sign in to facebook or something to save our progress because the game is fun but i get sad/angry that the game doesnt save progress, so basically you can play it once if you dont want to catch up to your progress i will be very happy if you add progress saving system

Hello, dear developers of the game. I really like your game, it has everything for a comfortable time spending. But it's just one thing that if you exit the game, the game progress is not saved. That really hurt my feelings because there are a lot of people who have bad Internet, and they fly, and they also reset the progress.
If you can, make system to save progress. Log in to the game in order to retain all that you have done over the period of the game.
Thanks for listening, I hope many will agree with me, and you are no exception!
Sorry for my English.

I posted this to another source.io sub, but the entire sub got nuked, so I thought this sub might benefit from it.

I just found this game yesterday and really enjoyed it when I started. As I got further into the game though, two things frustrated me:

There's no save when you leave

There's a TON of hacking.

This made me think that it might be a fun exercise to write my own bot for this game, so that's what I've done. It can be found on my Github.

Building a bot for this game has given me some insights on hacking, so I'd like to share some of my thoughts on ways to make hacking a bit harder.

All the words are images, so that's a good start, but unfortunately, the path is always the same. So my bot knows that when it sees /easy/4j22.png, that's going to be the word "user". I think fixing this is probably the easiest way to make hacking harder right now. Ideally, I'd want to programmatically create those word images.

Image noise. Since the words are already in images, you should add some noise to them to make OCR more difficult. I'm using a free OCR API, and it can identify your images correctly probably 90% of the time. That combined with predictable words from image paths means I can blaze through words REALLY fast with very little manual input.

Different types of input. It might be fun to make users do simple math problems occasionally. It makes the game a little bit different which might be fun, but it also makes OCR a little bit more difficult.

Throttling. I'm not sure how quickly I can submit word guesses, but I know it's pretty darn fast. I think it would be worth timing the guesses, and if they occur too quickly, do something about that.

More rules. If my bot goes wacky and enters the wrong guess 10 times in a row, extremely quickly, I should get disconnected. I shouldn't get to keep guessing until I get it right.

IP Banning. I think this is probably one of the most powerful ones. If someone breaks one of those rules (like exceeding the rate limit), you should IP ban them for some amount of time. I think ideally, it would be only 15-30 minutes, but you can increase that with repeat offenses.

Overall, I think it's a fun game with promise. I hope my writeup helps you deal with the hacking issue.
